IMPROVEMENT IN APPARATUS FOR OPERATING AND LOCKING SWITCH-SIGNALS.

Specification forming part of Letters Patent No. 161,940, dated April13, 1875; application filed March 1, 1875.

To all whom it may concern:

Be it known that I, SMITH H. FINoH, of the city, county, and State ofNew York, have invented anew and useful Improvement in Apparatus forMoving and Looking Switches and Signals, of which the following is aspecification This invention relates to new and useful improvements inapparatus for the management of railroad-switches and signals, wherebymany advantages are secured and much danger avoided; and it consists ina system of levers and locking devices, arranged substantially ashereinafter described.

In the accompanying drawing, Figure 1 is a plan view, and Fig. 2 avertical section of Fig. 1 taken on the line 00 or.

Similar letters of reference indicate corresponding parts.

A represents a frame for the support of the levers and locking devices.This frame may be of any size, and constructed to accommodate anydesired number of levers. B B are the levers for locking, and G O arelevers for moving, the switches or signals. These lovers are made towork from one side to the other side of the frame, and lock and unlockthe switches and signals thereby. D are lockingbars provided with twoshoulders each, which catch and hold the levers, as seen in the drawing.These locking-bars have at each end a portion turned at a right angle,which portion is designated by the letter E, and through which portionsare pivot-bolts F, upon which the bars turn. These angular portions haveeach a slot, F, in their extreme ends, which engage with latches G H,which work in slots or mortises through the frame confined byjoint-pins. The latches G and H, are connected together by the bars I onthe outside of the frame which are parallel therewith. They are attachedto the latches by pivots so that the latter turn freely. The inner endsof the latches G are curved and slotted much like the end of anS-wrench, and receive a staple or plate, J, on the levers B B, andthereby hold the lever in a locked position, while the bars D are lockedby the latches H, which are thrown into the slots F, in the angularportions E. When the other lever B is unlocked the switch or signallevers G are locked.

The switches and signals (or either) are connected with the levers bymeans of wires, rods, or in any suitable manner. The levers areconnected with the frame by means of slotted stands J, and joint-pins K,as seen in Fig. 2, and are locked and unlocked when thrown to eitherside of the frame, as the case may require.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The locking-bars D, latches G and H, bars I, andlevers B G, in combination with a suitably-constructed frame for thepurposes described.
